Because it was previously agreed upon that we'd exchange gifts for birthdays and Christmas, dude. If that had changed for some reason, she should've let me know before I started Christmas shopping. She knew well in advance when I was starting to look for things and, what's more than that, expressed excitement when I would mention that I'd found "another perfect thing for you, can't wait for you to see it." ETC. She had plenty of opportunities to either tell me she couldn't get me something this year or ask to call off the gift exchange. I mean- I wouldn't have, but at least then I'd know her intentions?

As it stands, she's either lied to me, which bums me out severely because we promised not to do that to one another, or, as discussed in another thread, has the gift but hasn't sent it out of shame for being so late, which is why I'm trying to figure out how to gently approach the subject with her.
